GUIDE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 330,708, dated November17, 1885.

Application filed September 25, 1885. Serial No. 178,120.

To all whom it may concern:

Be it known that I, WM. H. JARVIS, of Ansonia, in the county of NewHaven and State of Connecticut, have invented a new Improvement inGuides for Rolling-Mills; and I do hereby declare the following, whentaken in connection with accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in

Figure 1, a section through the rolls of the rolling-mill at the groove,showing the inner face of one guide; Fig. 2, a front view of the rollsof the mill,showing the outer end of the two guides; Fig. 3,ahor'izontal longitudinal section of one of the guides.

This invention relates to an improvement in the guides used inrolling-mills to guide the rod or barinto the rolls. As usuallyconstructed, these guides consist of pieces of metal, generally abouttwo inches high, arranged one each side of the path of the bar into therolls. At their forward end they are reduced corresponding to the shapeof the rolls, and so as to enter between the rolls nearly to the pointwhere the rolls take the metal, as indicated at Fig. 1, the guidespresenting a flat smooth surface, against which the bar will run. Toproperly guide the bar or rods into the rolls, it is necessary that theguides should extend a considerable distance from the rolls, so as tolocate the rod in its proper parallelism with the grooves in the roll.The opening at the ends between the guides can only be substantially thewidth of the bar which is to be rolled, and the hot rod is liable to beabutted against the end of the guides in entering, so as to interrupt orinterfere with the proper introduction of the rod.

The object of my invention is to facilitate the introduction of the rod;to and the running of it through the guides; and it consists inconstructing the guides with a recess at (No model.)

their outer ends, upon the inner face, with a guide-roll arranged ineach of said recesses on a vertical axis, the face of the roll proecting slightly beyond the face of the gulde, as more fully hereinafterdescribed.

A represents one roll, and B the other roll, of a rolling-mill; C theguides, which are ill outline substantially of the usual form. At theextreme outer end, and upon the inner face, a recess, D, is cut, so asto leave an ear, b, upon both the upper and lower side. Into this recessa roll, E, is arranged on a vertlcal axis, its face projecting slightlybeyond the.

inner face of the guide, as shown, and so that the rolls appear at theentrance between the two guides, as seen in Fig. 2, and serve to receivethe bar between them, and so that should the rod abut against either ofthe rolls the roll will revolve and instantly turn the end inward. sothat little care is required in the introduction of the rod between-theguides, the rolls not only facilitating the entrance to the guides, butthe movement of the rod between the guides.

Two of these guides are arrangedone each side the grooves-in the rolls AB, through which the rod is to pass, and as seen in Fig. 2.

I do not claim, broadly, an anti-friction roll in guides forrolling-mills.

I claim The guide C for rollingmills, each constructed with a recess, D,upon their face and at their outer end, combined with a vertical roll,E, arranged in each of said recesses upon a vertical axis, the surfaceof the said roll exposed through the recesses at the outer end of theguides, substantially as described, and so that said rolls form theentrance between the said guides.

W. H. JARVIS.
